Nanocrystal-coated fibers might reduce wasted energy

Engineers at Purdue University have coated glass fibers with a new thermoelectric material formed by dipping glass fibers in a solution containing nanocrystals of lead telluride and then exposing them to heat in a process called annealing to fuse the crystals together. The resulting material is far less brittle and more effiicient to produce than conventional thermoelectrics.
